Application filed. June 18, 1912. Serial No. 704,481

To all whom it may concern:

Be it known that l, FREDERICK Lonmcn, a citizen of the United. States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in- Journal-Box Lubricantllevices, of which the following is a specificattion.

My present invention relates to an inn provement in journal-boflubricant devices of the kind shown and described in my application,Serial No. 6%,374, filed April 22nd, l912, in which the plate interposedbetween a spring-supportediubricant-holder and journal, islongitudinally cormgated to form a series of trough-lihhlubricant-chambers provided with rowsof perforations in their bases,which latter bear against the lubricant in the holder while the upperedges of the corrugations contact with the journal.

The object of my present improvement is to simplify the constructionthus outlined. and thereby adapt it for use, more particularly, on theshorter types of journals, by providing the perforations, for admittingthe lubricant from the supply in the holder into the troughdikechambers, at the ends of the latter.

In the accompanying drawing, Figure l is a view in longitudinalsectional elevation of a journal-hon equipped with my improvedconstruction of lubricant device. the

section being taken on line 1, Fig. 2; Fig. 2

is a, section on the irregular line 2-2, Fig. 1, and Fig. 3 is a planView of the corrugated plate.

The journal-box 4 and journal 5 therein may be of any desiredconstruction, with seats 6 formed on the bottom of thebon for the lowerends of two spiral springs 6, 6,. confined at their'upper ends in seats6 on the bottom of a follower-piste 7. This-plate is shown of dishedshape and provided with depending guide-flanges 7 on its lateral edges;arid it forms the spring-supported holder for the lubricating grease 8.Aplabe 9 of concavo-convex form, seating upon the grease 8', is providedwith depending guide flanges 9 to overlap the holder 7, and is formedwith a series of longitudinal corrugetions of the preferred V-shape incrosss ection illustrated, to produce parallel trough-like chemhets 10extending through out the length of the plate for contacting along'theirupper edges with the j-ournalsurface, to which. the plate conforms, andpenetration; at their lower edges the grease in the holder. Endwalls llconnect the depcndingliangcs and conform to the crosssectional shape ofthe piste; and. the journal beers against them as well as against theopexes of the plate-corrugations, the walls also preventing grease fromescaping at the ends of the chambers and beings/acted by dropping intothe journal-box.

The foregoing description applies both to the construction of saidapplication and to the present construction. instead, however, ofproviding lines of perforations in the lower apexes of the chambers M),i provide, in the present construction, perforations 10 onlv in theinner feces of the Wells 11 at the ends of the chambers, which Walls arehotlow, to become filled with the lubricant, and

have depending outer faces to overlap the ends oi the plate 7, forguiding purposes.

With the lubricant device in place in a jour Ell-b0X and containing;grease on the follower-plate, the pressure of the springs 6 forces thegrease into the curved recesses 11 under and formed by the hoilow Walls,and

from these recesses the grce the perforations 10 into a his the state ofthe prior-art Will permit.

What I claim as new and desire to secure by Letters Patent is-' 1. incombination witl av journal, a jam naLbox, ands lubricant devicecomprising a lubricant-holder spring-supported to exs Works through tendin the box below the journal and tend to rise toward it, and a concavo-'convex plate provided with a series of chamber-forming corrugationshaving 16- Wells containing openings for directing through themlubricant into the chambers 5 edges and at said walls with the journal.

2. In combination with a'journal, a journal-box, and a lubricant devicecomprising a lubricant-holder spring-supported to extend in the boxbelow the journal and tend 10 to rise toward it, and a concavo-convexplate provlded with a series of chamber-forming corrugations havinghollow end-walls containing openings in their inner faces for directinglubricant'in'to the chambers length- 1 wise thereof, said plate beinginterposed between said holder and journal to hear at the bases of thecorrugations against the lubricant and contact along their upper edgesand at said walls with the journal.

tend in the box below the journal and tend to rise toward it, and alongitudinally-corrugated concavo-convex plate forming a series oftrough-like lubricant-chambers, said platehaving depending side-walls,and hollow walls at; the ends of said chambers, forming bearings for thejournal, and provided with openings in their inner faces for directinglubricant into the chamberslengthwise thereof and with outer facesoverlap-' ping the ends of said plate.
